A monogram is the interweaving of two or more letters or other symbols into a pleasing and balanced design. Monograms have been engraved, applied and enameled on jewelry for centuries. They are often a feature of the design on signet rings and are a popular motif on lockets, cigarette cases, card cases, match safes, watches, pocket watches, watch fobs, key chains, cuff links and anything with a flat smooth area suitable for engraving.
